Methyl Cellulose in HPMC Applications for Improved Performance and Versatility
The general chemical structure of MHEC is presented in Fig. 2. According to supplier information, the sample employed in the study exhibited a degree of substitution relative to methylation (DS value) of 1.81, and a molar degree of substitution relative to hydroxyethylation (MS) of 0.15. Gel permeation chromatography (GPC) analysis produced molar masses of 2.48·105 g/mol (Mw) and of 1.74·105 g/mol (Mn), respectively (Table 2). Using the GPC method, a hydrodynamic radius Rh(z) of 31.0 nm and a
One of the primary applications of MHEC in the pharmaceutical industry is as a binder in tablet formulations. Tablets are a popular dosage form due to their convenience and ease of administration. MHEC acts as a binder by providing cohesion and adhesion to the tablet ingredients, ensuring that the tablet maintains its shape and integrity. This is particularly important for tablets that are intended to be swallowed whole, as they need to withstand the forces exerted during swallowing.
Youngcel can be used as plasticizer in Ceramic Extrusion. It can fasten hydration speed and increase expansion index of the ceramic.
